Not for all of the time rangers will win though. All classes can win, but it depends on the other side and teammates.
-Berserker gets owned by wizards and necros
-Paladin gets owned by wizards and necros (AND SOMETIMES AN ASSASSIN[depends on lvl bracket tho, example i pwn many pallies 1v1 even a 43 pally])
-Ranger gets owned by berserkers
-Assassin gets owned by berserkers and wizards (why wiz? cause the lating of their skills just always pop us out from Stealth!)
-Wizard gets owned by rangers, assassins, rushing zerkers, sages (maybe)
-Necro gets owned by mostly all the classes....beside slow killing classes
-Sage gets owned by Ranger!!!!! assassin berserker
-Cleric gets owned by every class
PS:these are just in my thoughts. and other thing is all classes can get owned if you are more than 3 or 4 on 1 attacking, stunning, or whatever. OKIE my thoughts are my thoughts, please dont complain it thank you seriously...
